Materials Data on TeWSe by Materials Project

WTe2WSe2 is Molybdenite-derived structured and crystallizes in the trigonal P3m1 space group. The structure is two-dimensional and consists of one WSe2 sheet oriented in the (0, 0, 1) direction and one WTe2 sheet oriented in the (0, 0, 1) direction. In the WSe2 sheet, W4+ is bonded to six equivalent Se2- atoms to form distorted edge-sharing WSe6 pentagonal pyramids. All W–Se bond lengths are 2.58 Å. Se2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms. In the WTe2 sheet, W4+ is bonded to six Te2- atoms to form distorted edge-sharing WTe6 pentagonal pyramids. All W–Te bond lengths are 2.72 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms. In the second Te2- site, Te2- is bonded in a 12-coordinate geometry to three equivalent W4+ atoms.

There are three shorter (2.72 Å) and three longer (2.73 Å) W–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 3-coordinate geometry to three equivalent W4+ atoms. In the second Te2- site, Te2- is bonded in a 12-coordinate geometry to three equivalent W4+ atoms.
